Abstract:

The conservation strategy goal is to strengthen plant communities with high biodiversity. Wadis are one of the important
areas of Tehamah region (Saudi Arabia) sheltering a rich diversity of higher plants. The study area is extended approximately
upto 100 km2 encompassing the commonest geomorphological features encountered in desert Wadis. The studied Wadis
(Khedran, Rash, Maleil) support several rare plants, including a regionally endangered tree, Acacia ehrenbergiana Hayne,
Atriplex hortensis L., Anisitus risoolaus L. and Aerva javanica L., a rare shrub with restricted distribution. The present study
aims to maintain their existence and health for which a management system must be established. The vegetation type is
fundamentally of chamaephytic in nature with some phanerophytes, and is distinguished into associations where the dominant
perennial species give the permanent character of plant cover in each habitat. The three vegetation groups above mentioned
were identified and named in Chaudary’s book with the main associates identified as Cassia acutifolia Mill., Calotropis procera
L. and Aerva javanica L. These plants with their associations demonstrate significant variation in soil texture, moisture, organic
matter, pH, EC, and minerals of Wadi Mangal. Many measurements and calculations were done. Pioneer data was recorded for
these three Wadis.
